You job is to analyze this process. You are told the following information: a. 1000 kg of coffee beans are loaded into the mixing tank at a time and the beans are 98.4 wt% coffee solids and 1.6 wt% caffeine. b. 95% of the caffeine in the raw beans is removed with the caffeine loaded solvent stream from the mixing tank. c. The rotary dryer removes 95 wt% of the remaining solvent in the decaffeinated coffee beans but does not remove any additional caffeine. d. 85% of the solvent fed to the mixing tank leaves in the caffeine loaded solvent stream. e. The solvent evaporated from the beans and leaving the dryer is condensed and collected and is found to 50.00 kg

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
